Wouldn’t you like to know what that is? Maybe you will, eventually. Not in this book though. [Editor’s note: If you see it spelled “Adonasium” anywhere, that is an unfortunate typographical error.]

The Mechanism of Hemalurgy

The Blessings and the workings of Hemalurgy gave me some trouble as I designed the second and third books of this series. On one hand, I liked the way Hemalurgy worked by stealing powers from Allomancers or Feruchemists and giving them to other people. However, if I was going to limit myself to sixteen metals and be able to steal both Allomancy and Feruchemy, that meant I needed a mechanism to determine which power got stolen. If, for instance, you drove a pewter spike into a person who was both an Allomancer and a Feruchemist, then how would that spike know which power to suck out and grant to the one who would gain it?

As I was toying with how this would work, I realized that I needed to work the kandra and the koloss into this as well. Only, it was ridiculous to assume that the Lord Ruler would kill Allomancers to make koloss. There weren’t enough Allomancers, for one thing—plus it would be foolish to lose the power of an Allomancer to gain an inferior tool in a koloss.

So that meant koloss had to be made out of regular people, not Allomancers or Feruchemists. Suddenly I had another set of abilities that Hemalurgy had to be able to steal—the basic pieces of Preservation inside the souls of all men.

Hence the decision that where the spike was placed in the receiver, and how it was used to kill a person, influenced how the power was shaped. Now a pewter spike could steal any of a number of powers, based on how it was used. And regular people could be used instead of Allomancers—however, when that happened, the receiver was twisted much more than if an Allomantically charged spike or a Feruchemically charged spike was used.

My rationale for this is that if the spike is pulling out the pure power of Preservation—part of the power of all creation—and twisting it, it would change the body of the recipient greatly. Twisting them through use of the twisted power.

The Blessing of Stability

It’s mentioned in this chapter, and in the preceding chapter’s epigraph, where the epigraph author notes that it is “rarely used.” There’s a simple, rational reason why you never see this one getting used in the book.

I added the Blessing of Stability after the fact.

You see, I realized that I needed at least one more Blessing to fit with what I’d built for Hemalurgy. I needed another mental power to complete the set of four. Two are the basic physical powers from Allomancy and Feruchemy: strength and fortitude from one, increased power of the senses in another. However, for Allomancy and Feruchemy, the mental powers deviate from one another. So I wanted the same thing to happen here. Hence the Blessing of Presence—which makes the mind more stable.

But after writing the book, I realized I needed a forth. The Blessing of Stability was born, and I wrote it in in a few places just to make token note of it. I like the concept for the power—that of making one emotionally stable—and am kind of glad I don’t show anyone using it. I can show it off better in a later book.
